...Moisture will increase in the Southwest ahead of Hurricane
Priscilla over the next few days and bring a threat of flash
flooding...

Some influx of moisture is forecast to continue across portions of
Arizona and New Mexico today with a weak front at the surface.
This will lead to scattered showers and thunderstorms for these
areas, and a Marginal Risk (level 1/4) is in place for isolated
flash flooding potential today, with burn scars at particular
risk. Into Thursday, moisture from what is currently Hurricane
Priscilla is forecast to continue streaming northward and produce
locally heavy rain across the Desert Southwest into the Four
Corners region, with isolated instances of flash flooding. This
will only be the start, as heavy rain and flash flooding potential
from Priscilla`s moisture should continue across the Southwest
late week into the weekend.

Farther east, rain will be ongoing today across the Eastern
Seaboard as a cold front passes through. Precipitation will clear
by this evening into tonight across the Northeast and
Mid-Atlantic, while some scattered showers and thunderstorms could
continue in the Southeast and south into Florida into Thursday.
The Atlantic coast of Florida could see a rainfall focus on
Thursday into Thursday night, with isolated flooding possible
particularly for urban areas. Meanwhile in the Pacific Northwest,
shower chances will spread inland today into Thursday ahead of an
incoming frontal system, with the chance some snow may mix in for
some of the higher mountain peaks.

The cold front moving through the East will cool temperatures to
feel more like Fall today and especially by Thursday, when highs
in the 50s are forecast for the Northeast and 60s should extend
into the Carolinas. Cold low temperatures could drop near or below
freezing from the Upper Midwest and Great Lakes into the
central/northern Appalachians and parts of the Northeast/northern
Mid-Atlantic this morning and Thursday morning, prompting Freeze
Warnings and Watches and Frost Advisories. Meanwhile above normal
temperatures are likely across the Intermountain West into the
northern Plains today, expanding into the rest of the central U.S.
Thursday as an upper ridge builds. This will yield highs in the
70s and 80s, with low 90s continuing in parts of Texas. The West
Coast can expect temperatures to cool due to a cold front, however.
